There is no single official average rent increase for Wexford, and advertised rents are not the same as lawful increases for existing tenants. Under current national rent-control rules, most private tenancies can generally be reviewed no more than once every 12 months, with the increase limited to the lower of 2% or inflation, subject to exceptions and transitional rules. Your landlord must give the required written notice, normally at least 90 days. Check the latest RTB guidance and rent calculator, or speak to a solicitor if the proposed increase appears unlawful.
